Nanoplasmonic devices, capable of confining light into ultrasmall domains well below the operating wavelength, bear great promise for novel energy technology applications, such as plasmonic photovoltaics or plasmonic water splitting. The theoretical description of such systems, however, is very challenging: it requires the combined modeling of the classical characteristics of the plasmon, captured by the Maxwell equations of electrodynamics, and its quantum nature, which is described by Schrödinger's equation. In the proposed project, we will develop a novel theoretical and computational framework for the description of electronic excitations, such as plasmons or magnons, in contact with complex environments. We will apply this approach to study fundamental processes in plasmonic, magnonic and photoelectrochemical systems und use our insights to suggest improved design principles for future energy conversion and information technology devices.

能够将光限制在运行波长以下的超质域的纳米塑料设备对新型能源技术应用（例如等离子体型光伏或浆液水分裂）具有巨大的希望。但是，这种系统的理论描述是非常挑战：它需要由麦克斯韦电动力学方程捕获的等离子体的经典特征及其量子性质的结合建模，这是由Schrödinger's方程描述的。在拟议的项目中，我们将开发一个新型的理论和计算框架，以与复杂环境接触的电子兴奋（例如等离子或镁质）的描述。我们将采用这种方法来研究等离子，磁和光电化学系统中的基本过程，并使用我们的见解来提出改进的设计原理，以供未来的能源转换和信息技术设备。
